C[Black 9: My favourite line of the ‘taisha’ - black 7 is well \
placed to spoil the eyeshape of White’s group.]
LB[fp:7]

;B[dm]
C[Black 19: It would be nice to play 21(A), but white would cut \
at 29(B) and win the capturing race in the corner.]
LB[cn:B][fq:A]
;W[fo];B[fq];W[ep];B[ip]
C[Black 23: Leaves many weaknesses, it would be better to play \
one point to the left.]
;W[ck];B[el];W[bm];B[bn];W[cm]
;B[cn];W[dj];B[gl];W[hn];B[jo];W[im];B[km]
C[Black 35: I was planning to build a large moyo on the right but \
this is pushing too hard - better would be to extend to 51(A) \
or to play on the third line on the lower side.]
LB[fi:A]
;W[fk];B[fl];W[hk]
C[White 38: Overplay - he is trying to shut the black group in \
to make me add an extra stone in the corner but this is unreasonable \
- 38' should be one point to the right.]
;B[gk];W[gj];B[fj];W[hj];B[dk]
C[Black 43: Better at 50(A) - black is straining too hard to get \
sente.]
LB[ej:A]
;W[cl]
C[White 44: Better at 51(A) - white is straining too hard to make \
Black add a stone in the corner.]

C[Black 49, White 50: Both better at 51(A).]

C[Black 49, White 50: Both better at 51(A).]
LB[fi:A]
;B[fi];W[eh]
C[White 52: 53(A) is impossible since Black would cut above 30 \
and kill many stones.]

;B[ar];W[kl];B[jk];W[kn]
C[White 62: He has to play here - the white group dies first if \
he starts a semeai. The result is not bad for White, though - \
even after 65(A) black’s lower side is weak.]

;B[qo];W[pp];B[oo];W[np];B[qk];W[kc];B[jd]
C[Black 75-99: Both sides strain as hard as possible - the issue \
is not so much whether Black lives in the corner as what happens \
on the outside while he is doing so. If 98' is at 99, Black plays \
below 91 saving his two stones 93 and 95 and getting a big centre.]

C[White 100: Both players have been waiting for this one - Black’s \
overplay at 23 comes home to roost.]
LB[ip:23]
;B[iq];W[ir];B[jr];W[hr];B[hp]
C[Black 105: Misses the best play - this should have been at 133(A), \
White cannot reply one point above (Black would descend at 106(B) \
and kill)- so he would have to cut at 145(C), allowing Black \
to cut through the centre, securing his stones absolutely. This \
would separate six white stones in the centre, and with weakish \
stones in the centre White would be unable to invade the right \
side deeply. Thus Black would get compensation for sacrificing \
his two stones.]

C[White 114, 116: These two stones are White’s profit from his \
attack, now 118 becomes a severe invasion and Black has little \
chance of getting enough territory.]

winning.]

C[Black 157: Ludicrous - this is a straight loss of two points.]

;B[bh];W[ch];B[ri];W[pm];B[on];W[nl];B[mh]
C[Black 165, 169: Unreasonable, but I was not interested in playing \
safely for a small loss.]

answer to the right.]

C[White 194: Black resigns - please confirm for yourself that the \
Black group is unable to make two eyes.]
